The end of my PhD is in sight and my post-PhD plans include the possibilty of some microISV action. So I need an auto-update plan for a WinForms app. I'm using WiX to deploy the app originally since the app includes fancy things like windows services, not just xcopy.

Basically I need it to grab a WiX generated patch file. Stop the app (after prompting the user) and prompt for admin credentials (if necessary) before starting the patch.

I've been looking around and I can't find any auto-update solutions I can use out of the box. So it looks like I'm going to have to write my own :( or at least adapt one of the current solutions.

Anybody got some better ideas?
